Censuses provide population numbers, household or family size and composition, and information on sex and age distribution. They often include other demographic, economic and health-related topics as well. The 1973 Colombia de facto census collected data through face-to-face interviews on the subjects of housing, household demographics, employment for individuals 10 and older, education for those 5 and older, migration, and fertility for women 15 and older. The census day was October 24, 1973. While fieldwork was done on the census day in urban areas, it was extended in rural areas, the Northern Territories, and remote areas of the country.
